ITZQS'E-COUELING j jglggig Snecificction of 3.. tiers Estonia. ffiaivg-ggiefi A333, 2? 19115;

To 6:15 whom may coco-em Be it known on: i, ERNEST ll. Won. :T a citizen of the Suited filtrates, residing at Point Pie" State of eer. Virginia, have invented a new and useful Hose-Coupler. of which lihe following is a specification. t

The present invention relates to improvements in hose couplers, and relates more pcrticulsrl to hose couplings for, train pipes, either for carrying steam or air, one object of the invention. being the provision of a coupler of the Sewali iype, in which a positivelOCli is provided, such look under the normal jarring of'the parts due to the,

been provided with locking bolts hav ng variously designed means for bringing such bolts into play to produce the desired looking effect. All ofthese locks have the objecti'on that it requires too much time to manipulate the same in assembling and disconnecting the mating couplings. T he present locl: has therefore been designed to permit of the rapid manipulation thereof both i in looking the mating connectors and in re leasing such connectors.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combinationand arrangement of parts. and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made Within the scope of What is claimed Without departing from the spirit of the invention.

In the drawings-Fig'ure 1 is a top plan View of two mating connectors assembled,

the h ing pin of one being removed. Fig. 2 is a side elevation of one of the connectors with izhe port portion in sccition. dotted lines ilhistrating the position of ihe two lockin; pins. Fig. 3 is a perspective View of a. complete coupler. Fig. l a section taken on line H of Fig. l, the pins being in "uni, in the county oflvlason and Sari-c2110. 863,950.

locking posiiion. Fig. 5 also side elevation of two inching connectors in the posicion they assume when being disconnected or connected. Fig. 6 is a cross section through one of the locking pins.

Referring to the drawings. A and B designate the two-mating couplers, each one of which is identical in construction, shore fore the description of one will suffice for both.

The body portion 1 of the coupler is provided with the hose connecting member 1',

the member 1 and hose conncctor 1 being provided with a channel 2 therethrou gh for the passage of fluid. A ort ring 3 mounted in the outer end the channel 2, as clearly illustrated. in Fig. 2. Annrm l is formed integral with the body '1 and extend long'itudinally thereof at one side thereof while formed integral with the body 1 at the opposite side thereof is the lug provided with the cam gr oovcb, and the straighclug 7 having the inner straight face 8 which is at righs angles to the face of. the body 1 at such point, and with the oppositely disposed grooved face 9. Y

The arm 4, as clearly illustrated in Fig. 3

is pro 'ided with the lug 10 hailing the straight face 11 and with the cam groove face 12 at theopposiie side, said lug 10 being disposed to coiipercte with the lug 5, as clearly illustrated in Figs. l, 4 and 5. While formed integral with the inner face of'the extreme end of the arm 4; isa projection 13,

provided with the grooved face l l which is adapted to oppose the groove 9 of the lug 7 so that both groove faces 9 and l lwill present a tapered bore receptacle for the tapered locking pin 15.

-E ach member carries its pin, through .the medium of the chain 16 and the connection 17 so the; the tapered pin may be inserted irom above between the respective lugs 7 and 13 and thus readily fall into position. It will thus be seenthat the gravity effect upon. the some due to she shaking of mating couplers will cause'the wedging pins 15 to be placed in greater Wedging relrition to the lugs 7 and 13, and thus more securely lock .the ports 3 into registration.

As the pins 15 are of greater length than the respective lugs between which they fit, the same may be readily're1noved,-l y the trainn'ian striking 'l'hc lower ends of the pins to drive then: upwardly. It will thus be seen that with this construci1on,tl1at a simple /'one carried by each -ti on from above between each arm and thepoints beyond the locking means as the '15 are provided cohperate with'theirespective lugs 7 and equ upon each side of "the cou' lers, that there will be notorsional stirs upon the;

port rings 3 andsuch' port rings 3 willbe held withequal strain upon both sides so as to insure the proper ahnement and; proper. registration thereof. 1

What is claimed is': 1. A direct port coupler,

portion and a longitudinall adapted to overlap with-the the mating member,

between each arm and bogiflto ,force the parts assembled, and a y removable gravity locked. tapered: pin carried by each memberfor wedgmg'the members to clamp themAindllockedrelation.1 I t 2. 'rect' ort coup er, 'avmg' 'ma ing members, each rnember of which-*has a'body portion and a longitudinally extended arm y portion or adapted to overlap with the body portion of 4 themating member, a guiding loekm means between each arm and body to hold t e arts from transverse movement and a tapere pm insertible from above and between the armof one member and the body portion of the other member forclamping the members in locked relation and held from longitudinal movement. p p

3. A direct port coupler, having mating members, each member of which has a body portion and a longitudinally extended arm adapted to overlap with the the mating member, l'oc -means between each arm and body to hol the parts from transverse movement, and two tapered pins,

member for interposibody portion of the mating members,'where-' by-the mating members are clamped at two ports and the locln'ng vmeans and held from longitudinalmove menu 1 z 4. A direct port coupler, having two mat-' ing members, each member of which has. a
